chased away because of what they have done. there hasn't been a full accounting or full consequences applied. and so that means, as rachel points out in the film itself, that this could happen again under another set of circumstances in the not too distant future. >> let me tell you, when i was in high school, the vietnam war was raging. and when the war ended, we all thought, well, gosh, as a country, we'll never do that again. guess what? that's why this documentary is so critically important for the generation following us to consume this and to understand how we were lied into this. what about that, rachel? >> i think, you know, ed, one of the things that ends up being important is the way that we describe to one another, even if it's not formal history, just our oral history about how we describe that as a country. and i think when you get down to the case that was made about why we had to go, it turns out that it was, as david puts it, a hoax. the case about why we had to go turned out not to be true. it was maintained to us as if it were true.
